Soit un module libre sur un anneau noethérien. Pour , soit l’idéal engendré par les coefficients de . Si est un élément de avec et si , il existe tels que .
Ceci généralise un lemme de de Rham sur la division des formes (Comment. Math. Helv., 28 (1954)) et on en obtient quelques applications à l’étude des singularités.
Let be a free module over a noetherian ring. For , let be the ideal generated by coefficients of . For an element with , if , there exists such that .
This is a generalization of a lemma on the division of forms due to de Rham (Comment. Math. Helv., 28 (1954)) and has some applications to the study of singularities.
